When I first put up a suet feeder, I hung it from a thin branch that I thought would not support a squirrel. In the past week or so, I have had to pick the feeder off the ground several times, and I suspected that a squirrel might be managing to knock it down. The last time I found the feeder on the ground, I replaced it and held it in place with a cable tie. (In case it isn’t obvious from the photo below, the feeder is hung from a bungee cord.) In the last couple of days, I’ve caught a squirrel too near the feeder for comfort. I think the feeder will be staying in place now, however.
